n00b much? If you have a legit copy of Windows you don't have to buy a key. Go to register your OS online and when it fails call the 1-800 # that flashes on the screen. You'll get an automated system that will ask you questions and you're good to go after nearly bangin your head through the top of your desk but once you get it set up you shouldn't have any more problems. Best of all you didn't have to pay a bloody cent above the initial cost. Works for OEM as well as Full Version.

Thanks for the OS suggestions....
I'm hoping to crank out some points over the 2-day FAT, so I am going to see how the 5870 fairs over the next two days - along with my FX-4100. I have to work a 16 tomorrow, so it will be set it and forget it before I leave for work. I am off Tuesday though, so I can watch it more closely for day two. Both the GPU and CPU have a mild overclock - 935MHz for the HD 5870 and 4162MHz for my FX chip, so hopefully I can put out some decent PPD! Good Luck to everyone who is participating!

I'm such a noob! I just spent a couple of hours installing (and getting familiar with) Ubuntu on my folding rig only to find out FAH doesnt have a GPU client for Linux! I have about 2 weeks until the Windows 7 will shut down due to no activation key. So much for trying to save $100....stupid Windows! Microsoft should introduce a simpler OS that is made specifically for folding and has very limited use otherwise. They could sell it for $15-20 and still come out ahead!

if you are really in a bind, I might be able to give you a hand. working as a contractor at microsoft has its perks, I can have a buddy get me a copy of win7 for their cost... if you really need it. Win7 pro (or ultimate, cant remember) is around $50. let me know if it comes to that.
